Manufacture progress for carbon ceramic brake disc using silicon carbide powder
1. Raw material-silicon carbide powder preparation: Select high-purity black silicon carbide powder/carbon fiber and ceramic powder as the main raw materials, and screen, crush, dry and other treatments to ensure the quality of the raw materials.
2. Material mixing: Mix the carbon fiber and ceramic powder in a certain proportion, add an appropriate amount of binder and lubricant, and mix them to make them evenly dispersed.
3. Molding: Pour the mixture into the mold, mold it by pressing or injection molding, and perform initial compaction.
4. Hardening and sintering: Put the molded carbon ceramic brake disc into a special furnace for high-temperature sintering treatment to make it react at high temperature and achieve a certain hardness and strength.
5. Machining: The sintered brake disc is machined, including turning, cutting and other processes, to make its surface smooth and flat, and meet the size and shape required by the design.
6. Surface treatment: The surface of the brake disc is treated by spraying, coating and other methods to improve its wear resistance, corrosion resistance and other properties, and increase the friction coefficient.
7. Quality inspection: The carbon ceramic brake discs produced are strictly inspected for quality, including appearance inspection, size inspection, hardness test, friction coefficient test, etc., to ensure the quality of the products.
8. Packing and delivery: The carbon ceramic brake discs that meet the quality requirements are packaged and sorted out for delivery to facilitate transportation and sales.
The above is the general production process of carbon ceramic brake discs. The specific production process may vary and be adjusted according to different production equipment and process requirements.
